Methane/Liquefied Petroleum (LP) Gas Sensors

For the detection of Methane

The sensing element is comprised of a sensing chip and an integrated heater formed on a silicon substrate using MEMS technology, and a metal-oxide semiconductor layer formed on the sensing chip. Due to miniaturization of the sensing chip, TGS 8410 requires a heater power consumption of only 0.087 mW(ave.), and is suitable for low-power equipment and battery-operated instruments. In the presence of detectable gas, sensor conductivity increases depending on gas concentration in the air. A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to the gas concentration.
